### SSH整合之实体类 ###

先写实体类：

package com.lkl.model;
    
    
    public class Emp {
    	
    	private int empno;
    	private String ename;
    	private String job;
    	
    	
    	public Emp() {
    		super();
    	}
    
    
    	public Emp(int empno, String ename, String job) {
    		super();
    		this.empno = empno;
    		this.ename = ename;
    		this.job = job;
    	}
    
    
    	public int getEmpno() {
    		return empno;
    	}
    
    
    	public void setEmpno(int empno) {
    		this.empno = empno;
    	}
    
    
    	public String getEname() {
    		return ename;
    	}
    
    
    	public void setEname(String ename) {
    		this.ename = ename;
    	}
    
    
    	public String getJob() {
    		return job;
    	}
    
    
    	public void setJob(String job) {
    		this.job = job;
    	}
    
    
    	@Override
    	public String toString() {
    		return "Emp [empno=" + empno + ", ename=" + ename + ", job=" + job + "]";
    	}
    	
    	
    	
    	
    }

然后写相应的 .hbm.xml,比如我的实体类是Emp,就写Emp.hbm.xml

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
    <hibernate-mapping>
    	
    	<class name="com.lkl.model.Emp" table="emp">
    		
    		<id name="empno" type="java.lang.Integer" column="empno">
    			
    			<generator class="sequence">
    				
    				<param name="sequence">emp_seq</param>
    			</generator>
    		</id>
    		
    		<property name="ename" type="java.lang.String" column="ename"/>
    		<property name="job" type="java.lang.String" column="job"/>
    	</class>
    </hibernate-mapping>
